                         (CSFR) to the growth of supermassive black holes. Considering that 
                         the evolution of the massive black hole is dominated by accretion 
                         (Soltans argument) and that the accretion process can be described 
                         by a probabilistic function directly regulated by the CSFR, we 
                         obtain the evolution of the black hole mass density. Then, using 
                         the quasar luminosity function, we determine both the functional 
                         form of the radiative efficiency and the evolution of the quasar 
                         duty cycle as functions of the redshift. We analyse four different 
                         CSFRs showing that the quasar duty cycle, d(z), peaks at z similar 
                         to 8.511 and so within the window associated with the reionization 
                         of the Universe. In particular, dmax similar to 0.090.22 depending 
                         on the CSFR. The mean radiative efficiency, , peaks at z similar 
                         to 0.11.3 with depending on the specific CSFR used. Our results 
                         also show that it is not necessary for a supercritical Eddington 
                         accretion regime to produce the growth of the black hole seeds. 
                         The present scenario is consistent with the formation of black 
                         hole seeds similar to 103 M? at z similar to 20.",
